I just discovered a big difference between the deadline shown on the Website and shown on the client. It is 1 Day difference ! I have checked this and it is the same for Atlas and Sixtrack, for other Sub-Projects I can not check. My clients are 7.6.33 and 7.6.22  Supporting BOINC, a great concept ! |

I remember this being discussed in the forums several years ago. No remedy was made about it. I couldn't find the message thread in question.

CMS deadlines also: Local: 2017-04-09:04:41:08 CEST Server: 2017-04-10:02:41:08 UTC The clocks will shortly change to DST but this does not happen at the same date around the world. It does not explain a one day difference but it may point to a general bug in the time calculation. |

The same procedure as last year! The CEST is correct for those tasks with end-time after the date when CEST begin. Edit: you see the same with one hour less at the end of Octobre. |

The same procedure as last year! Nope, it can't be the CEST, because the difference is 1 day, not 1 hour Supporting BOINC, a great concept ! |

It may skip a whole day due to a bug. Let´s crosscheck this with other projects. At the moment I have no WUs with deadlines after clock change (except CMS) and all of them show normal time calculation. If the calculations show errors in a few days and return back to normal after the clock change then it´s related to DST. If the error occurs only with LHC then it is a server problem, otherwise it´s unclear. |

Meanwhile I got a couple of WUs from other projects with due dates after the clock change. All of them show correct time calculations. The problem seems to be CERN specific. |

Meanwhile I got a couple of WUs from other projects ...... including ATLAS (unconsolidated server). The anomaly persists for CMS (only). |

I've seen that sometimes in earlier days with other projects too. The purpose is/was that the client will start running in high priority on time and is still able to return on time (24hrs spare time left) and a resend task from the project is not needed. |

@ Yeti ATLAS tasks from unconsolidated (1) or consolidated (2) server? Mine are from (1) as I do not (yet) run ATLAS from (2). @ CP I run a small buffer so my CMS tasks start immediately after they are downloaded. They are far away from the 24h border. |
